Gerbera is an important commercial cut flower that its vase life is usually short due to vascular occlusion. In this study, we assessed the effect of ethanol (2%) in prolonging the vase life, fresh weight, relative water uptake and some physiological and biochemical factors in the stem of two cultivars of gerbera cut flowers (‘Bayadère’ and ‘Sunway’). Ethanol extended the vase life of cut flowe...

A high frequency shoot organogenesis and plant establishment protocol has been developed for Gerbera jamesonii from ex vitro leaf derived callus. The optimal callus was developed on Murashige and Skoog (MS) basal medium supplemented with 0.4 mg L 6-benzylaminopurine (BAP), 4.0 mg L -naphthalene acetic acid (NAA) and 3% (w/v) sucrose. Two callus types differing in their structures and growth rat...
The plant pathogen Botrytis cinerea can infect undamaged plant tissue directly by penetration of the cuticle. This penetration has been suggested to be enzyme-mediated, and an important role for cutinase in the infection process has been proposed. In this study the expression of the cutinase encoding gene cutA of B. cinerea was analyzed using a cutA promoter-GUS reporter gene fusion. Transforma...
To determine the factors affecting airborne conidial concentrations of Podosphaera xanthii Braun and Shishkoff and powdery mildew severity in greenhouse-grown potted gerbera (Gerbera jamesonii H. Bolus), airborne concentrations of conidia were monitored in a glass and polyethylene greenhouse. Temperature, relative humidity, and leaf wetness were recorded onsite, and the percentage of foliage wi...
The color of horticultural shade nets is known to influence crop growth and quality because variations in the amount light. Four ornamental plant species (celosia, begonia, gerbera, fountain grass) were grown under aluminet, pearl, red plus black as control at 50% intensity for 8 weeks. Black had least transmittance (∼10% 30% ambient) within spectrum (620–750 nm), whereas greatest ∼70% 80%. Alu...
